• Surface mount configuration

Substitute Classification:

Direct Manufacturer Substitute: DTA114TCAT116 (Rohm Semiconductor) maintains identical electrical specifications and base product number (DTA114), with equivalent performance across all critical parameters. This component is classified as active and available in tape and reel packaging.

Similar Manufacturer Substitute: MMUN2115LT1G (onsemi) provides equivalent electrical performance with enhanced power dissipation capability (400 mW versus 200 mW) and improved DC current gain characteristics. This component operates within the same voltage and current ratings and shares the identical SOT-23-3 package footprint.

Parameter Comparison

Engineering Selection Recommendations

DTA114TCAT116 (Rohm Semiconductor) is the primary direct substitute for the obsolete DTA114TKA-TP. This component maintains identical electrical specifications across all critical parameters, including collector current, breakdown voltage, base resistor value, and saturation characteristics. The DTA114TCAT116 is classified as active and carries ROHS3 compliance certification. Selection of this substitute eliminates obsolescence risk while preserving circuit performance without design modification.

MMUN2115LT1G (onsemi) serves as an alternative substitute with enhanced performance characteristics. This component provides superior power dissipation capability (400 mW versus 200 mW) and improved DC current gain (160 versus 100), while maintaining compatibility with the 50 V collector-emitter breakdown voltage and 100 mA maximum collector current ratings. The MMUN2115LT1G is classified as active and carries ROHS3 compliance certification. This substitute is suitable for applications requiring enhanced thermal performance or improved gain characteristics.

Both substitute components are available in active product status with unlimited moisture sensitivity level (MSL 1) and full regulatory compliance. Pin-to-pin compatibility with the SOT-23-3 package ensures direct board-level substitution without layout modification.
